Hej Stefan,

thanks for the suggestion -- through a Apache proxy the upload does indeed work without problems.

Cheers,

Hanno

That's strange. Might have to do with the SSL library elog uses. I just tried this forum (actually the "Demo"), and it worked fine through SSL, but I use an Apache proxy server for elog implementing the SSL protocol, which might be slightly different.

Hej,

I discovered a problem uploading images taken with the cameras of mobile devices to new elog entries directly from said devices. When selecting the image and choosing "Upload", either the blue page loading indicator gets stuck at around 10% (mobile Safari, iOS 8.3, iPhone 4 and iPad mini) or the error message "failed secure connection; connection reset while page was being loaded" ("Fehler: gesicherte Verbindung fehlgeschlagen. Verbindung zum Server wurde zurueckgesetzt waehrend die Seite geladen wurde") appears shortly after (Android 5.02, Firefox 37.0.2, Motorola G).

From the desktop browser (Firefox 38.0.5, OSX 10.10) there is no problem uploading images at all.

So far, this problem is very reproducible, but only when using ELOG with SSL enabled. Without SSL, the problem disappears on all platforms.

The ELOG daemon runs under Linux (Fedora 18) and I have also tried using the latest development version of ELOG.

Running ELOG with debug messages the only output after the page has been loaded is:

TCP connection #0 on socket 4 closed
TCP connection #0 on socket 4 closed

After these, there is no further output and the mobile devices do not indicate any progress either even after many mi.

The minimal config file I have been using is:

[global]
; network
port = 443
SSL = 1
URL = https://my.server.somewhere/
; paths
Logbook dir = /usr/local/elog/logbooks
Resource dir = /usr/local/elog
Logfile = /tmp/elog.log


[demo]
Attributes = Author, Type, Category, Subject
Required Attributes = Author, Type
Options Type = Status, Modification, Problem Report, Problem Details, Problem Fixed, Other
Options Category = Facility, Experiment, IT, Other
List Page Title = $logbook - $subject

As mentioned before, removing the first three lines fixes the problem (the URL line points to my actual server of course).

I would appreciate any pointers on how to debug this further! The functionality of posting images directly from mobile devices is quite important for the planed deployment of ELOG and I would very much prefer to have SSL enabled when doing so.

 

Thanks and cheers,

Hanno
